NOTES
•
Lines 5-8 and 22-23 are not available for NTSC video format.
•
Raw Data option is a field designated for monochrome 4:2:2 samples
(ETSI EN 301 775). The monochrome sample data coding is included in
order to manage VBI-information transfer and signaling standards that are
not supported by the unit. The encoder can use the monochrome 4:2:2
mechanism to encode any single VBI line, as long as no chrominance
information is involved.
•
Raw Data is available for C/V interface only.
•
When working with a UE-9000 unit with both C/V and SDI video
interfaces, the VBI headers are currently supported for the SDI interface
only. The supported VBIs are: WSS, Teletext, VPS, and CC.

VBI Bit-Rate Calculation
The VBI elementary-stream's bit-rate consumption is dynamic, changing
according to the number of lines and fields in use. The bit-rate consumption is
also affected by the Video Format mode (PAL or NTSC, see Section 6.1.1).
The VBI bit-rate calculation is most important now, as the encoder cannot add
elementary-streams if the total bit-rate of the ESs will exceed the transportstream's output rate (see Appendix D). If the user wishes to add another line to
the VBI, the user must know how to calculate the VBI's current bit-rate and
future bit-rate (after adding the new line).
NOTE
Each VBI odd or even line is considered as a single line. This means that
enabling a line's (for example line 22) both odd and even rows is considered as
enabling two lines, and the calculation is for two lines.
